Photosynthesis and climate change

Question 1

relationship between photosynthesis and cellular respiration

Answer 1

photosynthesis provides the carbohydrates and oxygen for cellular respiration to take place

Question 2

What is the very basis of life on earth?

Answer 2

photosynthesis

Question 3

What happens to oxygen in photosynthesis?

Answer 3

it is oxidized

electrons are pulled further away from oxygen

Question 4

What happens to carbon in photosynthesis?

Answer 4

it is reduced

Question 5

Where does the water come from for photosynthesis?

Answer 5

the soil

Question 6

Thylakoids

Answer 6

formed by the internal membranes of chloroplasts

Question 7

Grana

Answer 7

stacks of thylakoids

Question 8

Thylakoid membranes contain…

Answer 8

large quantities of photoreactive pigments

Question 9

Stroma

Answer 9

the fluid filled space between the thylakoids and the inner membrane

Question 10

Primary producer / autotroph

Answer 10

synthesizes its own food from inorganic sources

Question 11

Gross primary productivity

Answer 11

total amount of chemical energy produced in a given area and time period

Question 12

Net primary productivity

Answer 12

remaining energy that is not lost through cellular respiration within plants

gross - cell resp

Question 13

Consumers

Answer 13

eat living organisms

Question 14

Where is energy primarily used?

Answer 14

90% is used for cellular respiration or is unused

only 10% contributes to biomass

Question 15

Keystone species

Answer 15

has a much greater impact on the distribution and abundance of the surrounding species than its abundance and total biomass would suggest

Question 16

What do changes in the keystone species create?

Answer 16

a trophic cascade

Question 17

What makes an ecosystem more stable?

Answer 17

biological diversity

Question 18

Climate

Answer 18

the prevailing long term temperature and precipitation in an area

Question 19

Weather

Answer 19

consists of specific short term atmospheric conditions of temperature

Question 20

What does variation of temperature and precipitation result in?

Answer 20

different biomes

Question 21

Terrestial biomes

Answer 21

regions characterized by distinct abiotic characteristics and dominant vegetation types

Question 22

Where does carbon naturally come from?

Answer 22

organisms

Question 23

How is carbon eliminated?

Answer 23

by plants

this is why deforestation is such a big problem
